Definitions

  • the present invention relates to a threaded spindle adjusting drive, e.g., a vehicle seat adjusting drive.
  • a threaded spindle adjusting drive having a combined axial/radial bearing is known to the applicant internally within the applicant's firm, which has a one-part bearing element made of metal that is used to support both axial forces as well as radial forces on a jacketed pipe.
  • the bearing element rests in the radial direction on the inner circumference of the jacketed pipe and in the axial direction on radially inward directed crimps of the jacketed pipe.
  • a disadvantage of the simple construction is the comparatively high weight, due to the fact that the bearing element is made of metal, as well as the difficulty of being able to adhere to tight tolerances in the manufacture.
  • An objective of the present invention is to provide a threaded spindle adjusting drive, the bearing system of which has on the one hand a simpler construction and on the other hand, if required, may be manufactured in a simple manner in a weight-reduced variant. In particular, it is to be possible to adhere more reliably to tolerances in the manufacture.
  • the present invention is based on the idea of providing two different components for supporting the axial forces and for supporting the radial forces on the jacketed pipe, which, however, may also be developed as a composite component, as will be explained later.
  • Providing two separate components, that is, an axial bearing element and a radial bearing ring makes it possible to develop the components from different materials.
  • the axial bearing element rests directly on a jacketed pipe, in particular of metal, that accommodates the bearing system inside, that is, on at least one crimp directed radially inward, preferably on multiple crimps of the jacketed pipe spaced apart from one another in the circumferential direction and directed radially inward. Since the compressive load per unit area is particularly high due to the small support surface formed by the front sides of the crimps, a specific embodiment is preferred in which the axial bearing element is developed from metal.
  • the crimping forces required for producing the crimps are decoupled from the radial bearing such that the crimping forces do not influence the narrowly toleranced bearing diameter. Consequently, it is possible to maintain specified tolerances reliably.
  • a further development of the present invention advantageously provides for the axial bearing element to be made of metal due to the merely small support surface on the jacketed pipe or on the at least one crimp of the jacketed pipe.
  • This is preferably a hardened metal, preferably a hardened steel, so as to ensure sufficient stability at high compressive loads per unit area.
  • the separation of the axial bearing element and the radial bearing ring thus makes it possible to limit the use of high-quality and heavy materials to those places where they are (absolutely) necessary.
  • radial bearing ring in which the latter is developed as an injection-molded plastic part.
  • a radial bearing ring developed in this way is not only simple and cost-effective to manufacture as a mass product, but also allows for small tolerances to be maintained.
  • the axial bearing element and the radial bearing ring are developed as a composite part, the axial bearing element being injection-molded into the radial bearing ring, for example, or being extrusion-coated in parts by the latter.
  • preassemble the axial bearing element i.e. to develop it as a composite component with the jacketed pipe.
  • mount the axial bearing element and the radial bearing ring in succession.
  • the radial bearing ring is preferably an injection-molded part from a thermoplastic plastic.
  • the drive gear developed particularly as a worm gear
  • the drive gear is connected either in a rotatably fixed manner to the threaded spindle or is connectible or is developed in one piece with the threaded spindle such that the drive gear is stationary relative to the threaded spindle.
  • the drive gear driven directly or indirectly via a transmission by a, in particular electrical, drive motor drives the threaded spindle in a rotating manner, a threaded nut sitting on the threaded spindle, preferably at a distance from the drive gear, which is connected to a component to be adjusted directly or indirectly, for example via a lever system.
  • the spindle nut By rotating the threaded spindle, the spindle nut is adjusted together with the component to be adjusted in the axial direction relative to the threaded spindle.
  • a specific embodiment is preferred, in which the threaded spindle and/or the drive gear rest(s) on the axial bearing element in the axial direction via a ball preferably situated on the longitudinal center axis of the threaded spindle.
  • the axial bearing element is preferably developed from a hardened metal.
  • a bearing receptacle for the ball is provided on the drive gear or on a component connected to the drive gear in a rotatably fixed manner.
  • the axial bearing element is developed as a, in particular, circular disk.
  • the outer diameter of the axial bearing element preferably corresponds, at least approximately, to the outer diameter of the radial bearing ring in order to allow for an installation inside the jacketed pipe. With its front side facing away from the threaded spindle, the axial bearing element rests in the axial direction preferably on multiple crimps of the jacketed pipe spaced part in the circumferential direction.
  • the threaded spindle adjusting drive is developed as an immersion spindle drive, that is, an adjusting drive, in which the threaded spindle penetrates the drive gear, which is preferably driven directly by an electric drive motor, in the axial direction.
  • the threaded spindle is preferably supported on one end in a rotatably fixed manner, the threaded spindle rotating in the axial direction relative to the drive gear when the drive gear is turned.
  • a component to be adjusted which is coupled to the threaded spindle, moves with the threaded spindle.
  • the drive motor together with the jacketed pipe and the worm gear are rotatably fixed in the system relative to the axis of rotation of the threaded spindle, the fastening bore in the jacketed pipe allowing for the drive motor to tilt together with the threaded spindle about a fastening bore axis, i.e. allowing for an angular adjustment.
  • the axial bearing element is preferably shaped as a ring and is penetrated in the axial direction by the threaded spindle.
  • annular axial bearing element does not rest directly on the drive gear, but rather only indirectly via the radial bearing ring, which preferably abuts on the drive gear in the axial direction, preferably on a ring shoulder of the drive gear.
  • FIG. 1 shows a threaded spindle adjusting drive in the form of a rotary spindle drive for adjusting a motor vehicle part.
  • FIG. 2 shows a threaded spindle adjusting drive in the form of an immersion spindle drive for adjusting a motor vehicle component.
  • FIG. 1 shows a threaded spindle adjusting drive 1 in the form of a rotary spindle drive, in this case a motor vehicle seat adjusting drive.
  • Threaded spindle adjusting drive 1 comprises a threaded spindle 2 having an external thread 3 , which mates with a spindle nut (not shown), which is connected to a component to be adjusted. By rotating threaded spindle 2 , the spindle nut is adjusted together with the vehicle part to be adjusted axially relative to threaded spindle 2 .
  • Threaded spindle 2 is connected in a rotatably fixed manner to drive gear 4 , which is developed as a worm gear and whose worm gearing 5 mates with a threaded gear worm 6 , which sits on a motor shaft 7 of an electric drive motor 8 .
  • Motor shaft 7 runs perpendicular to the longitudinal extension of threaded spindle 2 .
  • Jacketed pipe 9 has a through hole 11 having a circular cross section, which runs through the entire jacketed sleeve 9 at an axial distance from threaded spindle 2 in the transverse direction. Through hole 11 is used to fasten jacketed pipe 9 in a rotatably fixed manner in a housing and/or on the vehicle body (not shown). Jacketed pipe is able to tilt about the axis of through hole 11 , however.
  • Bearing system 10 comprises an axial bearing element 12 as well as a radial bearing ring 13 abutting on the latter in the axial direction.
  • Axial bearing element 12 and radial bearing ring 13 are developed as separate components. If required, these components may also be manufactured in one piece as a composite component.
  • a specific embodiment is likewise possible in which axial bearing element 12 is developed as a composite component together with jacketed pipe 9 .
  • Axial bearing element 12 is developed as an annular disk from hardened steel and rests with a front side 14 facing away from threaded spindle 2 in the axial direction toward the left in the drawing plane on multiple crimps 15 of jacketed pipe 9 , which are spaced apart in the circumferential direction and face radially inward. More precisely, front side 14 rests on front sides 16 of crimps 15 facing front side 14 . Crimps 15 are developed as radially inwardly directed jacket surface sections of jacketed pipe 9 , which were introduced into jacketed pipe 9 by applying a crimping force F v directed radially from outside toward the inside onto jacketed pipe 9 .
  • the disk-shaped axial bearing element 12 is developed as a stamped part, which has a front side 17 that is parallel to front side 14 but facing threaded spindle 2 .
  • Threaded spindle 2 and drive gear 4 are supported via a ball 18 centrally in the axial direction on front side 17 of axial bearing element 12 .
  • Ball 18 which is made of steel, is accommodated in a bearing receptacle 19 situated on the front side on drive gear 4 , which is developed as an injection-molded part. Alternatively, ball 18 may also be accommodated in a bore of the spindle and be fastened by crimping for example.
  • drive gear 4 rests with a circumferential section 20 on radial bearing ring 13 . Radial bearing ring 13 in turn abuts on inner circumference 21 of jacketed pipe 9 and braces the radial forces acting on drive gear 4 against jacketed pipe 9 .
  • FIG. 2 shows an alternative exemplary embodiment of a threaded spindle adjusting drive 1 .
  • the latter is developed as an immersion spindle drive in the exemplary embodiment shown in FIG. 2 .
  • FIG. 1 shows an alternative exemplary embodiment of a threaded spindle adjusting drive 1 .
  • the latter is developed as an immersion spindle drive in the exemplary embodiment shown in FIG. 2 .
  • drive gear 4 is penetrated in the axial direction by threaded spindle 2 , more precisely by an external thread section of threaded spindle 2 .
  • Stationary drive gear 4 has an internal thread 24 , which mates with external thread 3 of threaded spindle 2 . If drive gear 4 developed as a worm gear is driven to rotate by stationary drive motor 8 via motor shaft 7 and gear worm 6 , threaded spindle 2 is adjusted in the axial direction relative to drive gear 4 as a result of the threaded coupling with drive gear 4 .
  • Threaded spindle 2 also adjusts a vehicle component (not shown) attached to its end relative to drive motor 8 .
  • Bearing system 10 for supporting axial and radial forces comprises an axial bearing element 12 made of hardened steel, which has an annular shape in this exemplary embodiment. With its front side 14 facing away from drive gear 4 , axial bearing element 12 abuts directly on crimps 15 of jacketed pipe or their front sides 16 , which are spaced in the circumferential direction, and thus braces axial forces directly on jacketed pipe 9 . As in the exemplary embodiment shown in FIG. 1 , the outer diameter of axial bearing element 12 corresponds to the outer diameter of radial bearing ring 13 . Radial bearing ring 13 rests on the front side 17 of axial bearing element 12 facing away from front side 14 .
  • Radial bearing ring 13 in turn abuts on the one hand with its outer jacket surface on inner circumference 21 of jacketed pipe 9 and with its inner circumference surface on a circumferential section 20 of drive gear 4 , circumferential section 20 projecting into radial bearing ring 13 in the axial direction.
  • the radial extension of radial bearing ring 13 which is developed from plastic in the exemplary embodiment shown, is greater than the radial extension of axial bearing element 12 .
  • radial bearing ring 13 rests in the axial direction on a ring shoulder 26 of drive gear 4 .
  • Inner diameter d i of radial bearing ring 13 as well as the corresponding outer diameter d a of circumference section 20 are selected in such a way that ring surface 25 , by which radial bearing ring 13 is braced in the axial direction on drive wheel 4 , is sufficiently large such that a maximum compressive load per unit area of plastic radial bearing ring 13 is not exceeded.
  • the axial forces supported via ring surface 25 on radial bearing ring 13 are transmitted to axial bearing element 12 over the latter's entire cross-sectional surface such that here too the maximum admissible compressive load per unit area for radial bearing ring 13 is not exceeded.
  • the actual jacketed pipe support is then assumed by hardened axial bearing element 12 in the form of an axial bearing ring.
